AppDynamics agent fails on App Service on Linux (vmstat not found)

[kaushalp]

Issue

The instructions in the following document are incomplete
Configure AppDynamics for Java Apps (App Service on Linux)

The following error is seen in the logs:

[extension-scheduler-pool-5] 01 May 2019 23:20:42,271 WARN RawCollectorUtil - The collector script returned with these errors: ERROR: Failed to collect cpus, Unable to find vmstat command. Please check if vmstat is installed on this machine, or if the PATH environment variable is correctly configured
df: unrecognized option: l
BusyBox v1.28.4 (2018-07-17 15:21:40 UTC) multi-call binary.

Workaround

As the blessed image was alpine based, I worked around it by installing procps package.
apk add procps

Now the above is a pain as not there is no documentation on how to include the above command on start-up.

Possible Solution

Either update the document to include the right instructions or update the blessed image to have the right tools.

@kaushalp Thank you for raising this issue. I have made a ticket on our backlog to address this. In the meantime I will add a note in the documentation.
